Title: Acoustic touchscreen constructed directly on a cathode ray tube
Inventor: ARMSTRONG DONALD B
IPC: G06F3/041
Filed: 2000-03-23
Granted: 2002-01-01
Abstract: A touchscreen is constructed directly on the glass surface of a cathode ray tube (CRT). To solve the problem of insufficient space between the CRT's bezel and frontal region to accommodate the transducers for the touchscreen, the transducers are moved away from the frontal region, to the highly curved shoulder region of the CRT. To preserve acoustic signal strength, the positioning of the transducers is chosen to take advantage of the fact that an acoustic wave on a non-Euclidean surface travels along a geodesic path. Allowance is also made for the acoustic lens and prism effect of the corner regions of the CRT, where the transducer may be located.

Title: Low-wear and high-insulation gate valve collar
Inventor: LIOU JIN-KUEN
IPC: H01L21/00
Filed: 2000-07-14
Granted: 2001-08-11
Abstract: There is disclosed a gate valve collar manufactured by polyimide, instead of the brass used in the conventional skill. In the embodiment, the polyimide resin VESPEL developed by Dupon cooperation is used to manufacture the gate valve collar of the sputtering chamber. Because VESPEL has a better wear-resisting capability than brass product and also has an excellent insulating feature and a high lubricity, the use of VESPEL to replace brass and manufacture the gate valve collar can prevent the sputtering process from being contaminated by the brass.

Title: Reference gamma compensation voltage generation circuit
Inventor: SAKAGUCHI YOSHITAMI
IPC: G09G5/02
Filed: 2000-08-14
Granted: 2003-06-01
Abstract: The object of the present invention is to reduce the number of inputs to LCD driver chips, and to suppress the occurrence of variances between the chips. A ten bit wide binary counter 202 is self activated in synchronization with a system click. Each of multiple five-step shift registers 200 having ten bit widths stores gamma compensation data received from a PC. Each of multiple comparators 204 compares a binary counter value (X) with a value (Y) stored in a ten bit wide five-step shift register 200, and converts the gamma compensation data into a pulse width. The output of each comparator 204 is latched by each of multiple D-FFs 206 in synchronization with the system clock, and each of multiple time/voltage converters 208 passes the output of a D-FF 206 through an LPF and generates a reference gamma compensation voltage.

Title: Channel-type switching control
Inventor: MALMLOEF JIM
IPC: H04W28/18
Filed: 2000-11-28
Granted: 2002-05-21
Abstract: After a mobile user connection is assigned a particular type of channel, a sliding window with a predetermined number of time intervals is established for that connection. For each of the time intervals in that sliding window, information associated with the type of channel supporting the mobile radio connection is determined. The associated information may include one or more parameters including the type of channel currently supporting the connection, an amount of data to be transmitted for the mobile user connection, a requested quality of service, etc. The information in the sliding window is analyzed for a pattern or trend. Different patterns or trends may be used to assist in making channel-type switching as well as other decisions, e.g., power regulation. The analyzed sliding window information may be used both to determine when it is desirable to switch a user connection to another channel type and to prevent or reduce inefficient, excessive, or rapid switching of the user connection between different channel types.

Title: Method for compressing statistical data characteristics
Inventor: CHEN FRED H Y
IPC: H03M7/30
Filed: 2000-12-18
Granted: 2003-04-11
Abstract: The present invention provides a method for compressing statistical data characteristics. The method mainly applies statistical techniques to find data characteristics (such as the language unit of a dictionary datum and the repeat frequency of the language unit), and then, in accordance with the uniqueness of the characteristics, the datum is divided into several blocks. Furthermore, in accordance with a special pattern, the characteristics are arranged in sequence where each characteristic is given with a serial number for compression coding on these blocks. Each code is then replaced by a corresponding serial number, and the part without a characteristic in the datum is also coded in accordance with a Huffman compression algorithm. Thus, the required storage space can be minimized and, consequently, a higher data compression efficiency can be accomplished. Therefore, for extra large volume data, especially dictionary data having a high repeat frequency of language unit, the method can be applied for more efficient and effective data compression in an offline process.

Title: Colour display device
Inventor: VAN VROONHOVEN JOZEF CORNELIS
IPC: G09G1/28
Filed: 2000-12-20
Granted: 2002-01-01
Abstract: A colour display device (19) is disclosed with an improved focus performance. In present-day colour display tubes with DAF, the electron gun is provided with a second focusing electrode (25) driven with a dynamic voltage which is varied synchronously with the deflection field. The dynamic quadrupole lens formed between the first focusing electrode (23) and the second focusing electrode (25) is designed in such a way that the horizontal lens action, which arises when the voltage on the second focusing electrode is increased, should be compensated by the main lens which becomes weaker when the voltage on the second focusing electrode (25)is increased. In practice, it is not possible to achieve this in the required range of the dynamic voltage on the second focusing electrode (25), leading to a deterioration of the focus performance of the colour display device (19).This problem is solved by the present invention. By applying a dynamic voltage to the first focusing electrode (23), it becomes possible to focus the electron spots on the display window (3) in the horizontal and vertical directions, resulting in an optimally focused picture.

Title: Music distribution systems
Inventor: HUNTER CHARLES ERIC
IPC: G07F17/16
Filed: 2001-01-20
Granted: 2007-04-11
Abstract: Music is blanket transmitted (for example, via satellite downlink transmission) to each customer's user station where selected music files are recorded. Customers preselect from a list of available music in advance using an interactive screen selector, and pay only for music that they choose to playback for their enjoyment. An antipiracy ""ID tag"" is woven into the recorded music so that any illegal copies therefrom may be traced to the purchase transaction. Music is transmitted on a fixed schedule or through an active scheduling process that monitors music requests from all or a subset of satellite receivers and adjust scheduling according to demand for various CD's. Receivers store selections that are likely to be preferred by a specific customer. In those instances where weather conditions, motion of atmospheric layers or dish obstructions result in data loss, the system downloads the next transmission of the requested CD and uses both transmissions to produce a ""good copy"". In conjunction with the blanket transmission of more popular music, an automated CD manufacturing facility may be provided to manufacture CD's that are not frequently requested and distribute them by ground transportation.
